Complex Complex

  1. Mar 18, 2010 #1
    if a is a complex number which satisfy [tex]ia^3+a^2-a+1=0[/tex]

    then find [tex]\left | a \right |[/tex] ?

    one way is to put a=x+iy

    any other short way ?

    ok the real question was find the maximum value of [tex]\left | a -3-4i\right |
    [/tex]

    now will that help in any way making the soln shorter....i guess not..but still will it?
